Description

Technical Field

[0001] The invention relates to the technical field of construction, and in particular to a waterproof wall-penetrating sleeve structure and a manufacturing process thereof. Background Art

[0002] When constructing underground building structures, it is often necessary to embed sleeves on the side walls and then temporarily block them to facilitate subsequent drainage, sewage and firefighting work. When the embedded sleeves are needed, the temporary blocking port is opened, and then the through-wall sleeves are inserted and fixed on the side walls. However, in actual construction, workers often forget to embed the sleeves. In the prior art, workers will directly drill holes on the side walls and install the through-wall sleeves. The installed through-wall sleeves have poor waterproofing effects, and the sleeves often become loose and leak. Therefore, there is an urgent need for a waterproof through-wall sleeve structure that is easy to implement and has guaranteed quality. Summary of the invention

[0003] The purpose of the present invention is to provide a waterproof wall bushing structure and a manufacturing process thereof, which can be easily implemented and has a good waterproof effect.

[0004] A waterproof wall sleeve structure according to an embodiment of the present invention includes: a wall hole, which is opened on a side wall; a wall sleeve, which is inserted into the wall hole, and the left and right ends of the wall sleeve extend out of the left and right sides of the wall hole respectively, the left end of the wall sleeve is connected to a blocking plate, the outer wall of the wall sleeve and the inner wall of the wall hole are filled with sealant and waterproof mortar, a first waterproof layer is provided on the side wall at the left end of the wall hole, a second waterproof layer is provided on the outer wall of the left end of the wall sleeve, and the first waterproof layer and the second waterproof layer are overlapped by closing sealant; a polyurethane sealing tape, one end of the polyurethane sealing tape is adhered to the first waterproof layer, and the other end is adhered to the second waterproof layer; an annular steel plate, which is sleeved on the right end of the wall sleeve, a water-expanding waterstop strip is provided between the annular steel plate and the side wall, and the annular steel plate is fixed to the side wall by expansion bolts.

[0005] A waterproof wall sleeve structure according to an embodiment of the present invention has at least the following beneficial effects: when it is necessary to install the wall sleeve on the side wall, a wall hole is opened on the side wall, and then the wall sleeve is inserted into the wall hole. The blocking plate connected to the left end of the wall sleeve can prevent external water from entering the room through the wall sleeve. The sealant and waterproof mortar filled between the outer wall of the wall sleeve and the inner wall of the wall hole can effectively play a waterproof role and prevent water from leaking from the outer wall of the wall sleeve and the inner wall of the wall hole. The first waterproof layer and the second waterproof layer can To further increase the waterproof effect of the wall sleeve structure, the first waterproof layer and the second waterproof layer can increase the adhesion effect of the polyurethane sealing tape, and can effectively prevent the polyurethane sealing tape from falling off; the water-swellable waterstop strip will expand when it comes into contact with water, and can fill all the gaps between the annular steel plate and the side wall. Even if water accidentally flows out of the wall-penetrating hole, it will be stopped by the water-swellable waterstop strip and the annular steel plate; therefore, the wall sleeve structure has a strong waterproof effect, can effectively prevent the wall sleeve from loosening or leaking, and is convenient for workers to implement.

[0006] According to some embodiments of the present invention, one end of the polyurethane sealing tape is rectangular, and the other end includes a multi-segment strip structure, and the multi-segment strip structure is distributed along the length direction of the polyurethane sealing tape. In order to increase the waterproof effect of the wall-penetrating sleeve structure, the same polyurethane sealing tape should be used to stick on the first waterproof layer and the second waterproof layer at the same time. Since the axis of the wall-penetrating sleeve is perpendicular to the side wall, in order to effectively stick the polyurethane sealing tape, the other end of the polyurethane sealing tape is set to a multi-segment strip structure, which is conducive to sticking the polyurethane sealing tape on the first waterproof layer and the second waterproof layer, and also facilitates the polyurethane sealing tape to fit the second waterproof layer tightly.

[0007] According to some embodiments of the present invention, a metal hoop is provided at the left end of the wall sleeve, and the metal hoop clamps the polyurethane sealing tape tightly on the second waterproof layer, so as to ensure that the polyurethane sealing tape is closely attached to the second waterproof layer, thereby enhancing the waterproof effect.

[0008] According to some embodiments of the present invention, the metal hoop includes two semi-annular structures, which are connected by connecting bolts. The two semi-annular structures cooperate to clamp the polyurethane sealing tape, ensuring that the polyurethane sealing tape is closely attached to the second waterproof layer, and the disassembly and assembly are very convenient without damaging the polyurethane sealing tape.

[0009] According to some embodiments of the present invention, a notch is provided at the outer edge of the annular steel plate, and the tail of the expansion bolt passes through the notch, the water-expandable waterstop strip and the side wall in sequence. The expansion bolt is driven into the side wall from the notch, which causes less damage to the annular steel plate, and when it is disassembled and assembled multiple times, the wear and deformation of the annular steel plate is also relatively small, thereby increasing the service life of the annular steel plate.

[0010] A manufacturing process of a waterproof wall bushing structure according to an embodiment of the present invention comprises the following steps:

[0011] S1. Provide a wall sleeve and use a drill bit to drill a hole on the side wall so that the inner diameter of the hole is 20 mm larger than the outer diameter of the wall sleeve.

A first waterproof layer 120 is provided on the side wall 100 at the end, and a second waterproof layer 220 is provided on the outer wall of the left end of the wall sleeve 200. The first waterproof layer 120 and the second waterproof layer 220 are overlapped by a sealing glue; one end of the polyurethane sealing tape 300 is adhered to the first waterproof layer 120, and the other end is adhered to the second waterproof layer 220; an annular steel plate 400 is sleeved on the right end of the wall sleeve 200, and a water-swelling waterstop strip 500 is provided between the annular steel plate 400 and the side wall 100, and the annular steel plate 400 is fixed to the side wall 100 by an expansion bolt 600.

[0034] When it is necessary to install the wall sleeve 200 on the side wall 100, a wall hole 110 is opened on the side wall 100, and then the wall sleeve 200 is inserted into the wall hole 110. The blocking plate 210 connected to the left end of the wall sleeve 200 can prevent external water from entering the room through the wall sleeve 200. The sealant and waterproof mortar filled between the outer wall of the wall sleeve 200 and the inner wall of the wall hole 110 can effectively play a waterproof role and prevent water from leaking from the outer wall of the wall sleeve 200 and the inner wall of the wall hole 110. The first waterproof layer 120 and the second waterproof layer 220 can further increase the wall sleeve 20 0 structure, and the first waterproof layer 120 and the second waterproof layer 220 can increase the adhesion effect of the polyurethane sealing tape 300, and can effectively prevent the polyurethane sealing tape 300 from falling off; the water-swellable waterstop strip 500 will swell when it comes into contact with water, and can fill all the gaps between the annular steel plate 400 and the side wall 100.

In order to increase the waterproof effect of the wall sleeve 200 structure, the same polyurethane sealing tape 300 should be used to stick on the first waterproof layer 120 and the second waterproof layer 220 at the same time.

To ensure the waterproof effect, the total length of the polyurethane sealing tape 300 is greater than the circumference of the wall sleeve 200, and the length of the polyurethane sealing tape 300 stuck on the second waterproof layer 220 along the axial direction of the wall sleeve 200 is at least 150 mm.

[0036] In some embodiments, the left end of the wall sleeve 200 is provided with a metal hoop 700, and the metal hoop 700 clamps the polyurethane sealing tape 300 on the second waterproof layer 220. This can ensure that the polyurethane sealing tape 300 is closely attached to the second waterproof layer 220, thereby enhancing the waterproof effect. Figure 4 The metal hoop 700 includes two semi-annular structures 710, and the two semi-annular structures 710 are connected by connecting bolts 800. The two semi-annular structures 710 cooperate to clamp the polyurethane sealing tape 300, ensuring that the polyurethane sealing tape 300 is closely attached to the second waterproof layer 220, and the disassembly and assembly are very convenient without damaging the polyurethane sealing tape 300. Figure 5 In some embodiments, a notch 410 is formed on the outer edge of the annular steel plate 400, and the tail of the expansion bolt 600 passes through the notch 410, the water-expandable water stop strip 500, and the side wall 100 in sequence. The expansion bolt 600 is driven into the side wall 100 from the notch 410, which causes relatively little damage to the annular steel plate 400, and when it is disassembled and assembled multiple times, the wear and deformation of the annular steel plate 400 are also relatively small, thereby increasing the service life of the annular steel plate 400.
